PAPER-MAKING MACHINE.

,iication' filed July 11, 1910. Serial No, 571,412.

To all whom it may concern."

Be it known that I, WILLIAM C. Nws'u, a citizen of the United States,residing at Ne'enah, in the a county of Winnebago and State of\Viseonein, have iuvented'a new and useful Improvement in Paper-MakingMachines, of which the fd'lowing is a specifica- My invention relates toan improvement in the Fourdrinier or Harper shaking part of a papermaking machine, exclusively, and consists in removmg the shakingmovement from .that portion of the paper making machine which supportsthe dcckle frame, the duckies and slices, at. the end of the machinewhere the paper stock is delivered from the How box to the JR W1niachine wire b transl a e.

' fcrring the support of the deckle frame from the two shaking siderails of the machine frame to apart of the frame ofthe machine that isfixed, a part that. cannot be affected vin any manner-by the mechanismwhich ope'l'aies the shaking movement.

The manner in which this is actomplished shown in the accompanyingdrawing, in which,.

Figure lis-a side elcvationof that end of a paper making machine towhich the shaking movement is applied, some unimportant parts of themechanism, those that can in no way be affected by thcehangcs inconstruction which my invention requires, being omitted. Fig. 2 is atransverse section of thcmachiuc upotitlmmltne a, (not Fig. l, as

e i r t appears in looking toward the loft. Fig.

is a plan showing a part. of the fiowl box, the apronboard, the oils,and including the first dccklc frame connectingshaft, with my improvedmethod of supporting it. v

, Similar numerals and letters indicate like parts in the several views..It'Should be understood that my improvcment as here shown is forapplication to papcr'making machines already constructed,

they usually requiring special y made parts for transferring thesupports for the dcckle :frames from the shaking rails where they haveheretofore been supported, to a part of the machine frame which notshaken, and that in the construction of new machines, slight changes canbe niadc in the form of the dccklc frame connecting shaft journal boxesas here shown, which will be obvious to a paper mill machinist, thatwill lessen the cost of the improvement;

machine frame; 2, the pillar at the end of the frame to which theshakingmovement is applied, said pillar having a hinge joint 3, forpermitting the upper end of said pillar to oscillate transversely, and abar 3, above the joint 3 for connecting the pillars 1, indicates thebottom rail, or sill of the upon. opposite sides ofthe frame and causmgthe pillars to oscillate together.

:4, is a pillar upon which the upper side rails 5, are pivoted'upon thepivot bolts 6. 7, are intermediate supporting pillars under the rail 5;and S, pillars for supportinga save-all 9 under the nnichinc wire.

10, is a all suspended below the shaking rail 5, and in the present caseis shown 5 15 are mounted; 18, the flow box, from which the paper stockis delivered uponthe machine wire; 19, apron board extendng outward fromthe flow box upon which the stock iscarried b gravity to the Wire;

.20, elbows, or ells, at. aches to the How box andadjustable inpdsitio'n by means of hand wheels 20", foradaptinp, the width of fiow tothe width between the dccklcs; 21, a fieXi ble apron extending from theapron board forw ard upon the wire; 22, slices for gaging the thicknessof the the paper sheet.

, The shafts 14, which-connect the two side, frames 13, have heretoforebeen supported in journal boxes at their ends mounted upon stands underthem which were secured to.

the shaking rails 55 and consequently, the

decide frames, dcckles and slices, .which were connected directly to theframes and were mounted upon the rails 5,,receiVed the same degree ofshake as the wire and the rails 5. I y

For relieving the deckle frames and their attachments from said shaking,the boxes 23 are provided With an arm 24-, which ex tends downward and jthen horizontally and-is prqyided with aka-1 piece 25, which isfitmdtqandadjustably secured with a set scrw fifl, upon the upper: endof a pillar 27, which extends upward from the sill 1. The pillar beingerected upon the sill of the machine frame is unaffected by the shakingof the side rails 5. In this manner all shake to the deckle frames andslices is avoided, resulting in making a more uniform and smoother sheetof paper, as there is no springing of the slices on the deckle' frames.It will make a stronger sheet, as the fiber upon the upper side of thesheet will be drawn and Woven in a zig zag shape by the slices beingstationary and not having the motion of the wire. It will overcome foamspecks, as the churning of the stock between the slices .is avoided. No

' lumps will form on the slices or ells on apron, as there is no motionto them to cause it. It will be easier on the machinery and? decklestraps or hands. The paper will run safer, as theedges will be perfect,no tilting of the deckle straps or thin edges in the aper. It willrequire less power to drive the shaking mechanism.

" At the-left hand in Fig. 2, the cap piece.

25, is shown partly in section, it being made integral with the arm 24:and journal box 23, and bored for fitting around the stem 28 mas drinieror Harper type having the usual shaking rails, shaking Wire, and deckleframes, deckle frame connecting shafts, deekles and slices, arrangedabove the shale ing wire, a pillar upon a non-shaking part of themachine frame, a stem extending up ward from the upper end thereof, ajournal box fitted to and mounted upon a deckle ,t'rame connecting shaftand being provided with a cap piece or part adapted to be mounted uponand lllClOSG a part of the stem of the pillar aforesaid, and a set screwin said cap piece for adjusting the height of said cap piece upon saidpillar.
